THE SIDELINES : Hadingham to Give Up Tennis Post

LONDON — R. E. H. (Buzzer) Hadingham, chairman for the last six years of the All England Club, which runs the Wimbledon tennis tournament, will retire in December, officials said today.

Hadingham, who will be 74 when he retires at the club’s annual general meeting Dec. 14, said in a letter to friends and tennis associates that it is time “for a younger person to take over.”

Hadingham assumed the chairmanship from Brian Burnet in 1983. Under his leadership, covered courts and clay practice courts have been built and the grounds extended, and the “Last Eight” club was created for Wimbledon quarterfinalists.
